FIFA has been urged not to push through a decision on holding the World Cup every two years by CONCACAF, which called for all nations to be given chance to weigh in on the matter.

The current men's FIFA international match calendar ends in 2024 and Arsene Wenger is seeking to shape a new schedule in his role as FIFA's chief of global football development, but his plans have been met with opposition.

CONMEBOL said on Friday that South American nations are firmly opposed to a biennial World Cup, and CONCACAF – which governs the sport in North and Central America and the Caribbean – underlined the importance of all voices being heard in the debate.

A CONCACAF statement read: "Meetings between FIFA officials and the Confederation and, separately, CONCACAF Member Associations, will take place in the coming weeks.

"Our initial analysis is that we recognise the merits of creating entirely new international men's, women's, and youth football calendars which are underpinned by fewer international windows, reduced travel for players, friendlies being replaced by meaningful matches, and a more balanced structure for the overall benefit of football development globally.

"We will continue to look at these proposals constructively, with an open mind, and in the spirit of positive engagement.

"CONCACAF welcomes the fact that FIFA's chief of [global] football development, Mr. Arsene Wenger, has been transparent in sharing his vision and we are currently studying how the proposed changes would impact football in North America, Central America, and the Caribbean.

"While CONCACAF's immediate focus is on its own region, we also believe in the importance of being part of the global football family and we will listen to the views of football stakeholders in all parts of the world. It was in this spirit that CONCACAF was supportive of UEFA and its European football stakeholders when recent threats to their own club competitions structures were explored."

UEFA expressed strong opposition to the plans for a biennial World Cup, warning of a possible boycott if the plans go ahead.

While CONCACAF's statement did not show the level of clear opposition to the plans that came from UEFA and CONMEBOL, it urged caution nonetheless.

"Football in all parts of the world should be given an equal opportunity to play a part in the development of what is a FIFA international football calendar. Now is not the time for fearmongering and neither is it right that this process should be dominated by the interests of a few, or that more weight should be given to one particular region over others.  

"We encourage not only our fellow confederations but also all members of the global football family to come together and work collaboratively to create FIFA calendars and competitions that have benefits for the development of the game in all regions across the world."
